This is a frame shot of the Digital Video Essentials grayscale and ramp (Title 12, Chapter 14). This is how it should look when unaltered by the DVD player and converted straight to RGB.

DGIndex was used to capture this frame. Converted from CCIR601 to RGB, using Video levels (16-235) and with BTB and WTW information preserved.
